I Specification of Letters Patent, A Patented Dec. 21,1915. A

Application filed June 3, 1915. Serial Ho. 31,948.

To all whom it may concern:

Be it known that I, GRovnR O. SIsLER, a citizen of the United States, residing at Thomas, in the county of Tucker, State of West Virginia, have invented certain new and useful Improvements in Rail-Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This inventionrelates to improvements in rail clamps.

One object of the invention is to provide a clamp adapted for holding the meeting ends of a pair of rails whereby the use of fish platesand bolts is obviated.

Another object is to provide a device of this character which will hold the rails together in proper alinement, and will also prevent the creeping of the rails.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing: Figure 1 is a side elevation of a pairof rails held together by my improved rail clamp, Fig. 2 is an elevation from the opposite side, Fig. 8 is a top plan view, Fig. lis a section on the line 4-4 of Fig. 3, Fig. 5 is a section on the line 55 of Fig. 3, and Fig. 6 is a horizontal section on the line 66 of Fig. 4.

Referring particularly to the accompanying drawing, 1010 represents a pair of adjacent ties and 1111 the meeting ends of a pair of rails disposed across the ties and meeting at a point midway therebetween. A substantially U-shaped plate 12 is disposed between the ties and has outwardly directed upper ends 13 which are properly secured to the upper faces of the ties and on which the rails 11 rest. Spikes 14 are driven through these portions 13 of the plate and engage with the base flanges of the rails.

- Mounted in the U-shaped plate beneath the rails is a channeled block 15, one end of which is formed with an upwardly extending portion 16 forming a jaw which is I adapted'to bear against'one side of each of the rails at their meeting point.

' Mounted on the central portion of the blockdirectly'belovv' the rails is the upwardly extending lug 17 which projects vertically between the meeting ends of the rails and is adapted to hold the rails against creeping.

. Disposed through the block below the jaw member 16 is a threaded bolt 18. In the opposite vertical'walls of the channel are formed longitudinal grooves 19 which receive the longitudinal ribs 20 of a block 21 which is slidably disposed in the channel and forms the other edge of the clamp which is adapted tobear against the other side faces of the railends. The unthreaded end of the bolt projects beyond the block and is provided with a wrench engaging head 22. A plate 23 is secured to the adjacent end of the block and receives the bolt therethrough, said bolt being provided with a shoulder 24: for engagement with the plate to act as a stop for the bolt when it is turned to act on the movable jaw member '21. This last-named portion of the bolt is provided with a plurality, of ratchet teeth 25 engaged by a spring-pressed pawl 26-carried by the plate. This prevents the bolt from retrograde movement when it is turned up to draw the jaw members 16 and 21 into tight clamping engagement with the rails.

What is claimed is: v

1. A rail clamp comprising abase member disposed transversely under the meeting ends of a pair of rails, one end of the base member having-a rail base engaging face, the other end of the base member having a longitudinal channel and longitudinal grooves in the side walls thereof, a movable rail base engaging member having longitudinal ribs on the sides thereof and engaging in the said grooves, a bolt disposed longitudinally through the base member and threadedly engaged in the movable clamping member and means carried by the base member for engagement with the bolt whereby retrograde movement of the bolt is pre- Y ing a longitudinal channel and longitudinal grooves in the side walls thereof, amovable rail baseengaging member having longitudinal ribs on the side thereof and engaged v thessaid grooves, e bolt disposed longi fails for preventing the c reeping. 0f said tudinally through the base member and rail.
